Re: st: Matrix Algebra in Stata vs. SAS

[Stas Kolenikov <skolenik@gmail.com>]

I have not worked with SAS IML, but given that Stata is essentially
written in its internal matrix language Mata (including the -sem-
Stata 12 module, and -gsem- Stata 13 module), I seriously doubt you
can find a meaningful matrix operation that is not supported in Mata.
Stata -matrix- commands are somewhat more limited, although chances
are that you would be able to get away even with this limited
vocabulary. I have written my own -confa- confirmatory factor analysis
program using Mata, and did not face any restrictions in doing so.

I am taking a structural equation modeling course and the course guidelines indicate that SAS will be used for matrix algebra. I am more familiar with and prefer Stata over SAS and am trying to get a sense of whether or not there are any shortcomings that I might encounter using Stata to perform the matrix algebra that will likely be necessary for the course.  I have Stata 12.
